Melanotan II: a synthetic melanocortin receptor agonist with demonstrated melani
Melanotan II is a synthetic cyclic lactam analogue of α-MSH. This site does not list it in the 16-SKU catalog. The note exists so the name is not mixed with KPV (α-MSH 11–13) or with a tanning product.
RUO. Laboratory reagent listing. Not for human or veterinary use. Not a medicine, food, cosmetic, or supplement. Lot HPLC, MS, and net peptide content, when issued, live on the lot COA — we do not invent a percentage on this page.

Structural marks relative to α-MSH: norleucine in place of Met, D-Phe, C-terminal amide, and an Asp–Lys lactam. That is a different CAS from KPV and from afamelanotide (Melanotan I). It is not a cosmetic, not a tanning protocol, and not for sale here.
Related catalog peptide in the melanocortin neighborhood: KPV (tripeptide 11–13 only).
Confidence is the most beautiful thing you can wear.
